Dubbed either self-propelled semi-submersibles (SPSS) or low-profile vessels (LPVs), “narco subs” have gone from being a unicorn type of thing discussed only in Clive Cussler books to the real deal, especially when it comes to the Eastern Pacific, where they seem to be the vessel of choice running coke from South America to transshipment points in Central America.
Since they first started popping up in 2006, these craft have become an almost weekly thing in the past few years. The USCG and SOUTHCOM assets stopped almost 40 such boats in 2019, this number continued into 2020 where, across four days in mid-May Southcom stopped three narco submarines in the same week (remember the “Alto su barco” incident?), and showed no sign of stopping if you look at the typical patrols done by cutters throughout 2021-22.
Almost every recent EastPac patrol by the Coast Guard (or Fourth Fleet with a USCG LEDET aboard) shows off images of an LPV stopped with a gleaming white cutter in the background.
This translates into a whole series of art produced as part of the U.S. Coast Guard Art Collection in the past few years on the subject:
